Svelte
Svelte is a JavaScript framework that compiles to optimized vanilla JS for fast web apps with small bundles. Learn Svelte vs React, SvelteKit tutorials, and component examples.
Overview of Svelte
Svelte is a revolutionary JavaScript framework that changes how developers build web apps. Unlike traditional frameworks, Svelte shifts work to compile time, transforming components into optimized vanilla JavaScript. This compiler-based approach eliminates the virtual DOM, resulting in faster performance and smaller bundles. Svelte allows writing components with HTML, CSS, and JavaScript, delivering performance that often surpasses React and Vue.js.
Trusted by companies like The New York Times, Yelp, and 1Password, Svelte is production-ready for modern web applications. It ranks highly in developer surveys, with strong community support via Svelte Society and Discord. As free and open source software backed by Vercel, Svelte is a sustainable choice for projects across IDE and Build Tool categories.
How to Use Svelte
Start by setting up a new project with the official template or SvelteKit. Write components using standard HTML enhanced with Svelte's reactive declarations and stores. The compiler processes code during build, generating optimized JavaScript that updates the DOM efficiently. This workflow enables reactive apps with minimal boilerplate and excellent performance for static sites, server-rendered apps, and SPAs.
